LATH STRUCTURE Filed Feb. 11. 1929 Patented Mar. 22, 1932 PATENT JULIUSKAHN AND HERBERT E. WHITE, OF YOUNGSTOVYN, OHIO, ASSEGNORS T TRUSCONSTEEL COMPANY, OF YOUNGSTOWN, OHIO, A CORPORATION OF MICHIGAN LATESTRUCTURE Application filed February 11, 1929. Serial No. 339,085. g

The object of the present invention is to provide as an article ofmanufacture, a lath structure for walls, ceilings and the like that willconstitute an efiective support and back 5 ing for the plaster, andwhile providing for the proper keying of the plaster material, willreduce the amount of such material necessary to a minimum, whileproducing a satisfactory wall structure.

In the accompanying drawings:

Figure 1 is a front elevation of a portion of a lath structure made inaccordance with the present invention.

Figure 2 is a sectional view on the line 2-2 of Figure 1.

Figure 3 is a perspective view of a portion of the lath structure withthe plaster in place thereon.

Figure 4 is a vertical sectional view on the line 4.4 of Figure 1.

Figure 5 is a detail perspective view of one of the staples showing itsapplication.

Figure 6 is a rear elevation illustrating a staple after it has beenclinched.

In the embodiment disclosed. a backing sheet 7 is employed. Preferablythis sheet is made up of a number of plies of material, and consists ofa backing ply 8 that is rela tively heavy and rigid, so that itconstitutes the main body of the sheet.

There is a facing sheet 9 of material light in weight and these twosheets are secured together by an interposed waterproof layer 10 thatnot only constitutes the adhesive between the two outer plies, but actsto prevent moisture from the wet plaster reaching the rear supportingply 8.

The sheet 7, as a whole, is provided with rows of elongated depressions11, the open sides of which are on the side of the sheet having thelight facing material 9. As will be clear by reference to Figure 1,these depressions or pockets 11 are arranged so that those in each roware disposed end to end and those of one row are staggered with relationto those of the next. As a consequence the sheet is stiffened againstbending transversely of the pockets, that is to say the walls of thepockets constitute sectional reinforcing ribs, and by the overlappingrelation the forcing ribs on the rear of the plaster body section of onerib bridges the space between the ends of the sections of the others.

Located on the outer face of the backing sheet, to-wit, that facecarrying the light' ply 9, are wires or rods which we term lathrods.These are designated 12. Each rod 12 extends longitudinally along andover the pockets of one of the rows and is fastened by staples 13located between the ends of the adjacent pockets, the staples beingdriven through the backing sheet and having prongs 1% that are clinchedbeside each other as shown in Figure 6. i

This structure is nailed or otherwise fastened to the usual studding,and plaster as 15 (see Figure 3) is then applied. By reason of the factthat the rods preferably lie directly against the backing sheet, arelatively thin coat of plaster is sullicient and at the same timeeffective keys are secured by the plaster entering the pockets 11 andsurrounding the portions of the rods that extend over the same. Morethan that the plaster that enters the pockets forms thereby shortreinand these ribs being staggered act as stiffeners for the plasterlayer and indeed for ing material for the plaster.

From the feregoin it is thought that the construction, operation andmany acvantages of the herein described invention will be apparent tothose skilled in the art with- 0 out further description and it will beunderstood that various changes in the size, shape, proportion, andminor details of construction may be resorted to without departingfromthe spirit or sacrificing any of the advantages of the invention.

What we claim, is V 1. A plaster supporting structure C0111- prising abacking sheet having elongated depressions forming open sided elongatedpockets in one side of the sheet,'and lath rods located outside thesheet and secured to the sheet and extending longitudinally 7 over theopen sides of the pockets.

2. A plaster supporting structure comprising a backing sheet having rowsof spaced apart elongated depressions, thedepressions of one row beingstaggered with respect to adjacent rows, forming open sided elongatedpockets in one side of the sheet, and lath rods located outside thesheet and secured 'to the sheet and extending longitudinally over theopen sides of the elongated pockets.

3. A plaster supporting structure, comprising a backing sheet havingspaced elongated open pockets, lath rods located outside the'sheets andextending along the face, of the sheet and longitudinally over theelongated pockets, and fastening means located .between the ends of theelongated pockets and securing the rods to the sheets.

4. A plaster supporting structure, comprising a backing sheet havingrows of elongated open pockets, the pockets in each row pressions of onerow being staggered with respect to adjacent rows, lath rods extendinglongitudinally along the rows and located lengthwise over 'the elongatedopen sides of the depressions, and fasteners securing the rods to thebacking sheet.

8. A well structure comprising a backing sheet having rowsof'elongatedpockets, the

pockets of each row being located end to end in spaced relation andbeing staggered with respect to the adjacent rows so as to bridge thespaces between the adjacent rows, and lath rods located outside thesheet and extending longitudinally along the rows of pockets andlengthwise over the elongated open sides of the pockets.
